Aim: The aim of this study is to evaluate the performance, comprehensiveness, reliability, and quality of English-language YouTube videos related to new glucose sensor devices. Methods: In November 2024, a search was conducted on a computer using the keywords “glucose sensor devices,” “continuous glucose monitor,” “glucose sensor devices and Type 1 Diabetes Mellitus,” and “glucose sensor devices and child.” Based on the inclusion and exclusion criteria, 30 videos that met the research objectives were analyzed. Relevant URLs were recorded. For each video, the following information was collected. Results: Of the 30 videos analyzed, 40 % (n = 12) were presented or managed by healthcare professionals. The average values for performance features of the videos were: 172,257.166 ± 233,861.720 views, 170.866 ± 222.974 comments, and 1,643.133 ± 2,252.247 likes. Four videos did not receive any likes. 40 % of the videos contained good and useful information for viewers, while 60 % were of high quality. Conclusion: This study demonstrates that detailed and reliable content in YouTube videos about glucose monitoring devices enhances quality. It is recommended that video content be regularly evaluated, and future research should be conducted using alternative measurement tools in different languages.
